VeriSafe™ Absence of Voltage Tester
The Safe Way to Verify theAbsence of Voltage.
When servicing electrical equipment, workers mustcomply with safety regulations that require a voltage
verification test to validate the absence of voltage.
This process includes a number of stages that canbe complex and time-consuming when using
hand-held portable test instruments.
The VeriSafe™ Absence of Voltage
Tester from Panduit simplifies this process byautomating the voltage verification process.

VS-AVT

VS-AVT2

Once installed, a simple push of a button enables workers to verify the absence of voltage and see an active
indication when the absence of voltage is confirmed. This provides a new and innovative way to safely, reliably,and efficiently verify the absence of voltage before accessing potentially dangerous electrical equipment.
By automating this process, the VeriSafe™ Absence of Voltage Tester:• Reduces the risk of exposure of electrical hazards for improved worker safety• Reduces testing procedure time and complexity to improve productivity• Supports compliance when used to verify the electrical lockout/tagout
process as described in NFPA 70E
The VeriSafe™ Absence of Voltage Tester minimizes risk by verifying the absence of voltage before equipment
is accessed, making it easier for workers to verify an electrically safe work condition has been established in a
fraction of the time compared to using hand-held portable test instruments.

Multiple Environments

All VeriSafe™ Absence of Voltage Testers are tested to Type (UL, NEMA and CSA)
1, 12, 13, 4, 4X, IP66, or IP67 VS-AVT2 parts are rated to Class 1 Division 2, andClass 1 Zone 2 environments*The VeriSafe™ Absence of Voltage Tester satisfies the requirements for permanently mounted test devices describedin NFPA 70E-2018 120.5 (7) Exception 1 when it is installed in accordance with the ratings and instructions in theVeriSafe™ AVT Installation Manual.

Electrical Safety
Prior to performing de-energized work on electricalequipment, NFPA 70E requires that workers verify
equipment is in an electrically safe state. Until provenotherwise, equipment must be treated as energized andnecessary precautions must be observed.
One of the steps in the process of verifying that equipment
is in an electrically safe state involves a test for the absenceof voltage.

Verifying the Absence of Voltage
Before and after testing, the functionality of the tester must
be verified on a known source. When using a portable tester,
this is a time-consuming process and may involve exposure
to electrical hazards.
Using the VeriSafe™ Absence of Voltage Tester reduces riskand ensures the entire process is performed in the proper
sequence – every time, every test.

More than a Voltage Indicator
Voltage indicators warn of hazardous voltage, but cannot be used to confirm if equipment is de-energized. Absenceof Voltage Testers are permanently-mounted test devices designed to verify that a circuit is de-energized prior toopening an electrical enclosure containing electrical conductors and circuit parts.

RED indicators illuminate
when hazardous voltage
is present.

When AC voltage is not detected,indicators are not illuminated.
This does not guarantee theabsence of voltage.

Pressing the "TEST" button initiates
the voltage test, indicated by theflashing YELLOW caution indicator.

GREEN indicator illuminates
only when the absence ofvoltage has been verified.
